Determine the force P and the roller reactions at A and B.arrow_forwardDuring crash testing of an automobile, the lap and shoulder seat belts develop tensions of F = 260 lb. Treating the buckle B as a particle, determine the tension T in the anchor strap AB and the angle at which it acts. Use the force components method. Find the horizontal and vertical components T, and Ty. Use your solution for T, and Ty to determine the magnitude T and direction 0 of the anchor strap's tension. 60° F (Express your answer using three significant figures.)
